You can access this nested property as listed below:

Object Type Path to Holidays


Use the Holidays property, to manually populate the collection of holidays.

Alternatively, you can import holidays in the DevExpress Scheduler (.xml) or Microsoft Office Outlook® (.hol) formats from a file, via the WorkdaysOptions.LoadHolidays method.


If a date is defined as both a holiday (via the Holidays property) and strict workday (via the WorkdaysOptions.ExactWorkdays property), it is considered working day, and, consequently, it is not excluded from the axis scale.

For more information, refer to Data Aggregation.


This example demonstates how to exclude non-working days (weekdays and holidays) from an axis range, via the AxisBase.WorkdaysOnly and AxisBase.WorkdaysOptions properties.

using System;
using System.Windows.Forms;
using DevExpress.XtraCharts;
// ...
AxisX axisX = ((XYDiagram)chartControl1.Diagram).AxisX;

// Exclude holidays from the axis scale.
axisX.WorkdaysOnly = true;

// Specify custom working days.
axisX.WorkdaysOptions.Workdays = Weekday.Sunday | Weekday.Monday | Weekday.Tuesday |
    Weekday.Wednesday | Weekday.Thursday | Weekday.Friday;

// Specify holidays
axisX.WorkdaysOptions.Holidays.AddRange(new KnownDate[] {
    new KnownDate("Custom Holiday 1", new DateTime(1994, 3, 2, 0, 0, 0, 0)),
    new KnownDate("Custom Holiday 2", new DateTime(1994, 4, 2, 0, 0, 0, 0))});

// Specify strict working days.
// Thay will have a priority over the holidays specified.
    new KnownDate("Community Work Day", new DateTime(1994, 3, 2, 0, 0, 0, 0)));
